Closure System For Ball Mills And Method For Opening And Closing Ball Mills

A closure system for ball mills, wherein the ball mill comprises a grinding container with an end-face opening, which can be closed with a closure device, wherein the closure device comprises a first flange with first connecting devices and the end-face opening of the grinding container comprises a second counter-flange with second connecting devices, wherein the closing device can be fastened to the grinding container by means of the first and the second connecting devices, characterised in that the first or the second connecting devices are a component part of at least one rotatable, at least partially annular adjustment element, wherein the first and second connecting devices engage loosely through or into one another in an open working position of the least one, at least partially annular adjustment element, wherein the at least one at least partially annular adjustment element can be transferred by a rotation into a second closed locking position, wherein, in the closed locking position, the first and second connecting devices are rotated towards one another and wherein the closure system comprises means for producing a friction-locked connection, by means of which a clamped operative connection between the closure device and the grinding container can be constituted in a friction-locked manner.
